Megavoltage planning—level 4 Intracranial stereotactic radiation therapy (SRT) simulation and dosimetry for treatment planning, if: (a) all of the following apply in relation to the simulation: (i) treatment set‑up and technique specifications are in preparation for multiple non‑coplanar, rotational or fixed beam stereotactic delivery; (ii) precise personalised patient set‑up and immobilisation techniques are suitable for reliable imaging acquisition and reproducible SRT small‑field and ablative treatments; (iii) a high‑quality three‑dimensional image volume dataset is acquired in treatment position for the intracranial lesions to be planned and treated and verified; and (b) all of the following apply in relation to the dosimetry: (i) the planning process is required to calculate dose to single or multiple target structures and requires a dose‑volume histogram to complete the planning process; (ii) based on review and assessment by a radiation oncologist, the planning process maximises the differential between target dose, organs at risk and normal tissue dose; (iii) all relevant gross tumour volumes, clinical target volumes, planning target volumes and organs at risk are rendered and nominated with planning dose objectives; (iv) organs at risk are nominated as planning dose constraints; (v) dose calculations and dose‑volume histograms are generated using a validated stereotactic‑type algorithm, with prescription and plan details approved and recorded with the plan Applicable once per course of treatment
